Traditional Firewalls vs Next-Generation Firewalls – Reasons to Upgrade
March 27, 2017
Why do you need a next-generation firewall, when you already have a traditional firewall in place? The short answer: With new technology comes better security.
Limited capabilities and best effort traffic identification
Traditional firewalls can only deny or allow traffic based on IP addresses, port numbers and protocols. This method does not positively identify what the traffic really is and whether it has legitimate intentions on your network and should be trusted. Plus, IP addresses change all the time.
Added flexibility, control and efficiency
Next-generation firewalls recognize an application or website regardless of IP address or port numbers. The advanced filtering technology determines what kind of application it is and who is sending it, and makes intelligent decisions about which content and packets to block. With next-generation firewalls, you can also customize the filters to block by URL, content-type, risk-level, geographic location—you name it.
Continuous threat updates = better protection
The next-generation firewalls also include powerful anti-virus and malware protection. They continually and automatically update as new threats and vulnerabilities are discovered.
Nuvodia’s solutions include Cisco’s Firepower Threat Defense firewalls and Fortinet’s FortiGate firewalls. Both solutions have their own security intelligence labs that continually update their firewalls with developing threats and vulnerabilities discovered out in the wild on the internet.
Out with the Old. In with the New.
Next-generation firewalls can help ensure the integrity and privacy of your data, and availability of the network and services critical to your business. Our team at Nuvodia can help you transition from a traditional firewall to a more secure, adaptable and efficient next-generation firewall.
